Chronic wasting disease (CWD) is a sister disease to mad cow (bovine spongiform encephalopathy-BSE) -- just as Alzheimer's and CJD (Creutzfeldt Jakob) are similar human prion diseases.
Six million US Alzheimer's victims shed infectious prions to public sewers in their urine and feces. Meat packers and renderers discharge animal prion wastes to public sewers. Prions are found in human and animal mucus, blood, saliva, urine and feces. University of Wisconsin prion expert, Dr. Joel Pedersen, found that the wastewater treatment process does not inactivate prions - it reconcentrates them in the sludge.

Dr. Pedersen found prions can become 680 times more infectious when bound to certain soil minerals and survive for years. Human prions are 100,000 times more infectious than animal prions.

" . . . the species barrier from cervid to humans is prion
strain-dependent and humans can be vulnerable to novel cervid prion strains"

"Our results have far-reaching implications for human health, since they indicate that cervid PrPSc can trigger the conversion of human PrPC into PrPSc, suggesting that CWD might be infectious to humans."

Scientists identify the human strain as "CWD-huPrPSc".

In the July 3, 2010 issue of VETERINARY RECORD, Dr. Pedersen stated: “Finally, the disposal of sludge was considered to represent the greatest risk of spreading (prion) infectivity to other premises.”

Back in 2004, the CDC expected CWD to manifest only as Creutzfeldt Jakob Disease. But Nobel Laureate Stanley Prusiner recently pointed out the many
different strains of prion diseases:

". . . they (prions) are actually capable of
multiplying in what he terms "alternative" shapes, with
each shape responsible for a different type of dementia."

States may want to reevaluate their enthusiasm for sewer sludge spreading: The US Environmental Protection Agency (EPA) has identified infectious human and animal prions as emerging pathogenic contaminants of concern in sewage sludge "biosolids".:
